3 Claims. (Cl. 101-392) This invention relates to a stereotype chase for locking up Various printing material.

One of the main objects of the invention is to provide such a stereotype chase which is readily adjustable and in which the various and respective side bars of the chase are provided with a plurality of equally spaced slots for accommodating taper lock-up screws, whereby the chase is capable of quick and easy adjustment to accommodate various sizes of printing type and printing materials.

A further object of the invention is to provide one of the transverse side bars marked in columns while the respective longitudinal side bars have one marked in inches and one marked in picas to provide for guides in ready adjustment of the chase members.

A further object of the invention is to provide the respective side bars with trim lines to provide the matrix with markings for proper trimming.

A further object of the invention provides each of the side bars with a lip portion capable of receiving a corresponding overhanging lip portion at the ends of the respective side bars.

The particular chase described is more particularly used in setting up various combinations of cuts and type, stereos and type or any combination used to obtain stereotype job casts, prior to the moulding operation when preparing stereotype job casting.

At present when preparing printing material for moulding prior to casting, it has been necessary to use either a full page stereotype chase regardless of the size of the material to be moulded, in order to secure the printing type and printing materials firmly in the chase it has been necessary to till the unused portion of the chase with slugs, base or dead material and then build type-high bearers and bolsters around printing material to be moulded and locking the work with quoin key or taper wedge lock-ups.

In the present invention such prior uses are eliminated and the various printing material to be moulded is placed inside the chase, the taper lock-screws are inserted in the proper location to tit the size of the printing material to be moulded, and the taper lock-screws are then tightened locking the material firmly in the chase. Bolsters and trim lines are a permanent part of the chase.

The invention as illustrated in the accompanying drawing in which:

Fig. l is a top plan view of the chase;

Fig. 2 is a View in side elevation; and

Fig. 3 is a section on the line 3 3 of Fig. 1.

In the drawings in which like numerals have been used to indicate similar parts throughout the various views, the adjustable chase comprises a transverse side bar 6, said bar being marked in columns, a second transverse side bar 7 and longitudinal side bars 8 and 9, bar 8 being marked in inch designations while bar 9 is marked in pica designations, The respective side bars 6, 7, 8 and 9 are substantially identical in form and each includes a body portion 1@ being provided lengthwise thereof '2,779,274 Patented 1957 with` a recessed er inwardly directed flip `Pmiifm 1'1- The inner ends ofthe respective ,side bars areproyided with overhanging lip portions :12 which are .capable of and adapted to register with .the lipportions 11 and thereby provide bearing fsurfaces for the respective vside bars.

`Each of the bars alongtheir top Asurfaces are provided with identical 'trim lines 13 for designating yarious column Widths. and printing material .lengths and .Serve the Plit- Vpose of marking the matrix for proper trimming.

Further, each of the side bars is provided with a plurality of equally spaced slots 14 extending upwardly from the bottom side of the side bars, said slots terminating adjacent their outer ends, that is the ends directed to the outer side of the bars with the inwardly tapered surfaces 15. Each end of each of the side bars where the same are to be fastened to provide the desired size of the chase are provided with threaded recesses 16, said recesses capable of receiving a taper lock-screw 17, said lockscrew 17 being mounted within the desired slot 14 depending of course upon the size of the .chaseatdesirerL The taper lock-screw is provided with a head portion having a tapered portion 18 which is capable of cooperating with the tapered portion 15 of the slots 14, the head 19 of the lock-screw being provided with a through recess 20, said recess capable of receiving a. pin wrench (not shown) which of course is used for tightening the respective screws to lock-up the chase in any of its adjusted positions, and of course the pin wrench is also used to release or back olf the locking screws to enable the size of the chase to be varied at will. lt will readily be understood that in the adjustment of the respective side bars of the chase that it is unnecessary to remove the lock-up screws entirely from the threaded recesses 16, as it will readily be apparent that when the lock-up screws are backed off sufficient to enable the overlapping lips 11 and 12 to be separated the respective side bars need only be lifted and moved to their desired adjustable position. Of course this saves considerable time in the adjustment of the chase.

It is contemplated within the invention that a suicient number of side bars be provided to allow all sizes of printing type and printing materials to be locked in the chase in which, of course, it would. be necessary to substitute longer or shorter side bars determined by the size of the matrix to be locked.

In the use of the device when the size of the type matter from which the mat to be made has been determined, the respective side bars are placed in proper position after which the taper lock-screws are partly secured into the proper holes. After this type matter is inserted within the chase and aligned to meet desired requirements after which the lock-screws are then tightened with. the pin wrench, the type matter is now ready for the transfer to the matrix. After the matrix has been rolled the type can be released by simply loosening the lock-screws a sufficient distance so that the respective side bars can be disassembled. In consequence of the holsters and trim lines, the matrix is provided with means to facilitate the remaining operations.

While the invention is illustrated in one of its desired forms, it is contemplated that various modifications and changes might be made within the scope of the following claims.

I claim:

l. An adjustable chase comprising transverse and longitudinal side bars each of said bars being provided with a plurality of equally spaced slots, said slots terminating in tapered portions along the outside surfaces of the bars, each bar having at one of its ends a threaded recess and a locking pin mounted within one of the slots and engaging the threaded recess and having a tapered portion engaging the tapered portion of the slot.

2. An adjustable chase for locking up printing type and printing materials, said chase being provided with a plurality of identical side bars, said bars along their longitudinal inner surfaces having an inwardly extending lip, each of said bars having at one of their ends an overlying lip cooperating with the rst mentioned lip, said bars having a plurality of equally spaced cutouts terminating at their outer ends in tapered portions, each side bar having a threaded recess in the end in which the overlying lip is formed, and a tapered locking screw tting within one of the cutouts and engaging the threaded recess, the locking screw heads having a wrench receiving recess therein.

3. The structure recited in claim 1, said bars having trim linesy impressed along their upper surfaces.
